haha im a honda guy too, use to own a mad fast suoped up turboed 1.6L lol. did haul *** tho, major haulage. hondas are nothing like our nissan. forget your honda, its gone now and those headaches are over. go order a new intake manifold gasket for the top, and order one for the throttle body. dont re use that old crap its junk. take everything you did and re do it. take off every part put on , re do whole install. make sure u dont mess with the MAF sensor, its important. did u make sure to unplug ur battery b4 ur install? thats important too.

Although it can certainly be a leak, I'm thinking its more likely to be throttle body calibration related.

Scroll down to the bottom page of this link and try the reset procedures shown.

It can be very helpful in situations like yours.

 

lol!!!my bad for the comments about honda and **** but after 13 jager bombs it and a big cup of soco with coke....didnt realize the post..thats drunk grammer for you.....my bad sorry people

 

Come on guys, give the guy a break he used to drive a Honda and now a Z, he's moving up. lol

 

well it looks like he might be going back to Honda soon

 

ok no didn’t miss with the MAF sensor….but I did disconnect it when I was checking for any leaks in the hoses and none but I did reconnect the MAF sensor back in place and the old gasket back a place but DIDNT use the copper spray…the prior owner of the car had a injen cold air intake lmao suck up hella gunk build up over time going to post the pic of the dirt that **** did to the manifold build up like not changing the spark plugs, collocate brown oil , oil filter, and I think it still had the original belts from the factory hella cracking and **** barely notice the Nissan imprint.. what I have listed is what I have had done to the car in two week of own my z period to working a fulltime shift every day only had 3 days off using that time to clean and maintaining the to car up to date and that including the xmas I was working on the car that...lol

 

 

reset the ecu

R U STILL DRUNK?

 

Jagerbombs? fu**ing shower in that sh**!

First off never reuse gaskets, I don't care what people say don't be cheap. You do it once and you do it right. I own a mechanic shop and will never reuse gaskets. Second when you start it and the throttle jumps high, it sounds like something maybe stuck open hard to tell. And finally you need to use a real diagnostic computer to check your ecu and see what the hell is going on. Not some junk autozone CEL reset tool junk lol. Hope this helps and sober up before your F your **** up!

 

ok i cleaned the manifold,throttle body, MAF, change the gaskets upper intake gasket brand new oem, and throttle body gasket brand new oem, but the ses light keeps caming ON i did the 3 relearns then drove for 30min around town and the light came back on still cant figure the problem so i got a friend to get the code read and got P0507 thinking its a vaccum leak so i spray around the manifold with carb cleaner and double check the hose for cracks but nothing everything connected....need help my car is stock 350z

 

plug in your MAF....

 

holy run on sentence batman!

 

yea everthing is plug in...im thinking its the lower gasket but i didnt take the lower manifold part off??? but i sprayed the lower part with carb cleaner and nothing?? running out of ideas??

 

P0507 Idle Speed Control System

Its probably throttlebody calibration.

Do the reset procedure linked above. If that doesn't fix it, you may have damaged your throttlebody during the cleaning process. ...they are very sensitive.

 

Funny thing , it will look the same inside in a few thousand miles.
